专利等同侵权原则的实证研究

刘  强* 伍凌霄**

【摘要】随着专利保护所涉及的技术和侵权行为日趋复杂，等同原则也已经成为侵权判定原则中的重要组成部分。通过对等同侵权司法判决案例进行实证分析，可以为该原则的适用提供新的思路和视野。通过从等同侵权案件时间、地区、法院审级、专利主体、类型、技术特征覆盖程度等角度进行实证分析，发现等同原则在司法实践当中存在缺乏判定等同侵权具体的操作标准、法官自由裁量权过大、未对专利类型进行适当区分等问题。对于等同原则的适用，需要通过采取正确识别技术特征和选取判定方法，从严掌握该原则的适用，对该原则的适用对象进行适当区分，将覆盖技术特征的多寡作为适用标准等措施来进行完善。

The Empirical Analysis of the Equivalent Principle of Patent Infringement

Liu Qiang, Wu Ling Xiao

Abstract: Along with the patent protection of the technology involved and tort is becoming more and more complex, the doctrine of equivalent has also become an important part in the principle of determining the infringement. Through the empirical analysis of the equivalent infringement judicial decision case, new ideas and vision can be provided to apply it. Through the empirical analysis, including time, area, level of trial court, the patent holder, patent type, coverage of technical features, it is found that the doctrine of equivalents in the judicial practice is lack of determination of operability standards, excessive discretionary power of judges, and not properly distinguishing between patent types. For the application of the doctrine of equivalents, we need to take the correct recognition and feature selection method for judging, strictly control the application of the principle, properly distinguish the applicable objects on the principle, take the number of technical features covered as standards, and other measures to improve the application.
